ABSTRACT:
A FLOTOX EEPROM of the invention includes: a plurality of floating gates11arranged in array, each having a tunnel window12and allowing electron injection and extraction via the tunnel window; a plurality of select gates13provided in one-on-one correspondence to the plural floating gates11; a control gate16shared by the plural floating gates11; a source17shared by the plural floating gates11; and a drain18shared by the plural floating gates11. Therefore, the FLOTOX EEPROM does not encounter the decrease of junction breakdown voltage of a drain region, allowing the application of sufficiently high write voltage. Further, cell area can be reduced.
